For Part 1, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least copper(II) nitrate to the well with the most copper(II) nitrate. Which wells had the most distinct precipitate?

For Part 2, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(II) sulfate to the well with the most iron(II) sulfate. Which wells had the most distinct precipitate?

For Part 3, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(III) nitrate to the well with the most iron(III) nitrate. Which wells had the most distinct precipitate?

Answer:

Nitrate is a polyatomic ion with the molecular formula NO⁻₃ and a molecular mass of 62.0049 u. Organic compounds that contain the nitrate ester as a functional group are also called nitrates.

The color of the precipitate intensifies on moving from well 1 to well 9, as there has been an increased concentration of reactant and thereby the product.

  • The reaction of part 1 has been the reaction of copper nitrate with NaOH resulting in the formation of a precipitate of copper hydroxide. The precipitate has a blue color.

Thus, for the copper hydroxide moving from well 1 to well 9, the blue color intensifies.

  • The reaction of part 2 has been the formation of iron hydroxide with the reaction of iron sulfate with NaOH. The color of the precipitate has been dark green.

Thus, for the iron hydroxide moving from well 1 to well 9, the blue color intensifies.

  • The reaction for part 3 has been the formation of ferric hydroxide, with the reaction of Iron (III) nitrate with NaOH. The color of the precipitate has been red-orange.

Thus, for the ferric hydroxide moving from well 1 to well 9, the red-orange color intensifies.
